Non-adiabatic transitions in the density matrix formalism
Pasquale Di Bari, Shreya Pandit, Ye-Ling Zhou
We show that a density matrix formalism provides a useful description of non-adiabatic transitions in two-state quantum systems. Compared to a traditional Hamiltonian formalism, ev…
Boomerang mechanism explaining the excess radio background
Bhupal Dev, Pasquale Di Bari, Ivan Martinez-Soler +1
We propose a boomerang mechanism for the explanation of the excess radio background detected by ARCADE 2. In an early stage of the Universe, at a temperature in the range $\sim…
Majorana mass generation, gravitational waves and cosmological tensions
Pasquale Di Bari
A neutrino Majorana mass generation in the early universe might have left imprints in cosmological observables. It can source the production of a detectable stochastic background o…
Relic neutrino decay solution to the excess radio background
P. S. Bhupal Dev, Pasquale Di Bari, Ivan Martínez-Soler +1
The excess radio background detected by ARCADE 2 represents a puzzle within the standard cosmological model. There is no clear viable astrophysical solution, and therefore, it migh…
The split majoron model confronts the NANOGrav signal and cosmological tensions
Pasquale Di Bari, Moinul Hossain Rahat
In the light of the evidence of a gravitational wave background from the NANOGrav 15yr data set, we reconsider the split majoron model as a new physics extension of the standard mo…
Gravitational waves from phase transitions and cosmic strings in neutrino mass models with multiple majorons
Pasquale Di Bari, Stephen F. King, Moinul Hossain Rahat
We explore the origin of Majorana masses within the majoron model and how this can lead to the generation of a distinguishable primordial stochastic background of gravitational wav…
